Many tools are used in a household in a day, like lemon squeezer, pliers, metal clips, etc. But have you ever wondered how they are made what all processes they go through before reaching your households?

Various types of metals (that come out in magma) are extracted according to their different utilities and uses. Gold, silver, copper, steel, etc., are various metals and have different values. But these metals do not come in the shapes they are now in our households. Molding the metals into their desired shapes and uses is called press die casting. Students are taught about all this in their 8th or 9th grades in a chapter named metallurgy.

What is this process, and how does it happen?

The process of press die casting is not complicated at all:

1. The first step of the process is preparing the mold in which the hot melted metal is to be poured. The mold is first washed and clean. Secondly, the mold is applied with a special oil that acts as a repellant to the hot pored metal.
2. In the second step, the melted metal is poured or injected into the mold. The mold should be strong and rigid enough to hold the melted metal. The molten metal is then injected into the mold at a pressure of around 1,500 to 25,000 PSI.
3. In the third step, the extra molten metal in the liquid state is ejected from an ejector capable enough to carry the molten metal. Then the metal that is still in a liquid state and hot is left to cool down so that the metal is molded in the desired shape according to the purpose behind molding it.
4. Then in the fourth and final step, the molded metal is extracted from the scrap metal present inside the mold while separating it from the final product. The scrap metal is then shacked off from the mold for its reuse.

To recap the whole press, die casting: preparing the mold for the hot metal to be poured in it, then the hot metal is poured in the mold and then it is left for cooling down after rejecting the extra metal and the holding clips and then finally the product is separated from the mold. The mold is cleaned for another round. Not only metal but also plastic is molded for various utilities and uses by the same press die casting process. Moreover, some metals are mixed with plastic to increase their efficiency and durability in every kind of weather or state. This process is not new. This process used to occur when the nation was ruled by kings and had their currency. But the process now used is modified and corrected with the use of technology, and it’s much easier now.
